DOOR-SPRING.

$PECIFIGA'IION forming part of Letters Patent No. 595,245, datedDecember 7, 1897.

Application filed June 7,1897. Serial No. 639,769. (No model.) 1

To all whom it may concern.-

Be it known that I, WILLIAM HARGROVE, of the city of Chicago, in thecounty of Cook and State of Illinois, have invented a new and usefulImpro veinentin Door-Springs,whereof the following is a specification.

My invention relates to improvements in door-springs.

Figure 1 represents an elevation of a door and easing embodying myimproved doorspring. Fig. 2 is a section of the same on the line 2 2 ofFig. 1. Fig. 3 represents a de tail view of the arm and lever. Fig. 4.is a detail view of bracket, ratchet, and lever.

As shown in the drawings, the bracket C is adapted to be secured to adoor-jamb by means of screws and is provided on its under side withratchet-teeth c and a depending lug c.

A indicates a coiled spring, the upper coils of which embrace the lug o.

a is a part of a coil of the spring showing lever.

a is an arm which extends outwardly from the uppermost coil of thespring A and is bent back upon itself, thereby forming a spring-lever,the upper arm of which rests upon the upper face of the bracket C, whilethe lower arm engages the ratchet-teeth c on the under side thereof.

The arm a of the spring A is shown as sooured to the door-casing D by aneyelet cl, and on the end of said arm 60 1s a sharp point d, which isdriven into the casing D to hold the arm in proper position and keep itfrom slipping through the eyelet (Z.

The novelty of this invention consists in the construction of the devicewhereby it is operated without the aid of a wrench or pins. By raisingor lowering with the hand the lever in ratchet-teeth c a positiveactionis given to wind up coil-sprin g Aand give it the proper tensionto close a door equally small or large.

lVhat I claim as my invention, and desire to secure by Letters Patent,is-

The combination with a door and its casing, of a bracket adapted to besecured to the door and provided 011 its under side with ratchet-teethand a depending lug, a coilspring, the upper coils embracing said lug,and having an arm extended outwardly from the uppermost coil and bentupon itself to form a spring-lever, one arm of which rests upon theupper face of the bracket, the other arm engaging the ratchet-teeth, andmeans for securing said spring to the door-casing, consisting of the arma extended outwardly from the lowermost coil thereof and having aneyelet d, secured in the casing, and through which said arm may bepassed and held in place, substantially as shown and described.
